  • Method Detail

    * #### values  
    public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model")[] values()  
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:  
    for (SourceVersion c : SourceVersion.values())  
        System.out.println(c);  
    Returns:  
    an array containing the constants of this enum type, in the order they are declared  
    * #### valueOf  
    public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model") valueOf​([String](../../../java/lang/String.html "class in java.lang") name)  
    Returns the enum constant of this type with the specified name. The string must match _exactly_ an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)  
    Parameters:  
    `name` \- the name of the enum constant to be returned.  
    Returns:  
    the enum constant with the specified name  
    Throws:  
    `[IllegalArgumentException](../../../java/lang/IllegalArgumentException.html "class in java.lang")` \- if this enum type has no constant with the specified name  
    `[NullPointerException](../../../java/lang/NullPointerException.html "class in java.lang")` \- if the argument is null  
    * #### latest  
    public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model") latest()  
    Returns the latest source version that can be modeled.  
    Returns:  
    the latest source version that can be modeled  
    * #### latestSupported  
    public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model") latestSupported()  
    Returns the latest source version fully supported by the current execution environment. `RELEASE_5` or later must be returned.  
    Returns:  
    the latest source version that is fully supported  
    * #### isIdentifier  
    public static boolean isIdentifier​([CharSequence](../../../java/lang/CharSequence.html "interface in java.lang") name)  
    Returns whether or not `name` is a syntactically valid identifier (simple name) or keyword in the latest source version. The method returns `true` if the name consists of an initial character for which [Character.isJavaIdentifierStart(int)](../../../java/lang/Character.html#isJavaIdentifierStart%28int%29) returns `true`, followed only by characters for which [Character.isJavaIdentifierPart(int)](../../../java/lang/Character.html#isJavaIdentifierPart%28int%29) returns `true`. This pattern matches regular identifiers, keywords, restricted keywords, and the literals `"true"`, `"false"`,`"null"`, and `"var"`. The method returns `false` for all other strings.  
    Parameters:  
    `name` \- the string to check  
    Returns:  
    `true` if this string is a syntactically valid identifier or keyword, `false` otherwise.  
    * #### isName  
    public static boolean isName​([CharSequence](../../../java/lang/CharSequence.html "interface in java.lang") name)  
    Returns whether or not `name` is a syntactically valid qualified name in the latest source version. Unlike [isIdentifier](../../../javax/lang/model/SourceVersion.html#isIdentifier%28java.lang.CharSequence%29), this method returns `false` for keywords, boolean literals, and the null literal. This method returns `true` for _restricted keywords_ and `"var"`.  
    Parameters:  
    `name` \- the string to check  
    Returns:  
    `true` if this string is a syntactically valid name, `false` otherwise.

                                 [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model") version)  
    Returns whether or not `name` is a syntactically valid qualified name in the given source version. Unlike [isIdentifier](../../../javax/lang/model/SourceVersion.html#isIdentifier%28java.lang.CharSequence%29), this method returns `false` for keywords, boolean literals, and the null literal. This method returns `true` for _restricted keywords_ and `"var"`.  
    Parameters:  
    `name` \- the string to check  
    `version` \- the version to use  
    Returns:  
    `true` if this string is a syntactically valid name, `false` otherwise.

    Parameters:  
    `s` \- the string to check  
    Returns:  
    `true` if `s` is a keyword, or boolean literal, or null literal, `false` otherwise.

    Returns whether or not `s` is a keyword, boolean literal, or null literal in the given source version. This method returns `false` for _restricted keywords_ and `"var"`.  
    Parameters:  
    `s` \- the string to check
